protogastric region
A paired anterolateral area on the gastric region of the carapace of crabs [Chace and Hobbs, 1969].
The region on the dorsal surface of the carapace bounded by parts of the margins of the frontal, orbital, hepatic, epibranchial, metagastric and mesogastric regions [Ingle, 1983].
